Control systems are used to limit structural lateral deflections during large external loads such as winds and earthquakes. Most recently, the semi-active control approach has grown in popularity due to inexpensive control devices that consume little power. As a result, recently designed control systems have employed many semi-active control devices for the control of a structure. In the future...

Air cycle systems (ACSs) are primarily used in aircraft environmental control (ECSs) to provide a suitable cabin temperature and pressure environment for passengers avionics. It comprises heat exchangers, compressors, turbines, water separators, various other components that interconnected form an information-transmission network. Traditional research on ACSs has focused their thermal performan...

The standalone microgrids with renewable energy resources (RERs) such as a photovoltaic (PV) system and fast changing loads face major challenges in terms of reliability power management due to lack inherent inertial support from RERs their intermittent nature. Thus, storage technologies battery (BES) are typically used mitigate the fluctuations maintain balance system. This paper presents mode...

control of well drilling operations poses a challenging issue to be tackled. the loss of well control could lead to the occurrence of blowout as a severe threat, involving the risk of human lives and environmental and economic consequences. conventional proportional-integral (pi) controller is a common practice in the well control operation. the small existing margin between pore pressure and f...

in this paper, we try to use modeling based on singular perturbation theory, in order to control satellite attitude during the wide rolling angle maneuvering through nonlinear h∞ control strategy. differential equations describing dynamics of the satellite are presented first, and by choosing the appropriate dynamic model for actuators and based on the standard singular perturbation model, the ...
